.hpplice'sios. filed December To all 20710122; may concern Be it known that l, Guouos F. BUTTER- FIELD, of 'West Newton, in the county of Middlesex and Scte oi Massachusetts, have invented certain new and useful Improvement-s in Composite Soles end Solirig Metericl, of which the following is a specification.

The object of this invention is the production of new and useful composite soiiug and resilieula, and sdcptcd for use in the manufacture of boots and shoes generally. This mcieric I make up in sheets of any desired length or thickness and also in the form of? soles and of soles and heels.

In the drawing, Figure 1 represents, in perspective, a. slab or block of my soling meriai; Fig. 2 is a diagram showing the su ssivc layers to be united in its manuiiucture; Fig. 3 is a diagrammatic section showing the application of these soles and heels to 3. shoe, and Fig. 4.- a. bottom plan 'chorcof.

My improved soling material A, Fig. 1, of the following comgiosite structure, viz: c foundation sheet strong zextile :Echric suitably cleansed from. grease or oily substances by boiling in a strong solution of bomx, potash or other grcasc'destroying liquid, or by immersing in naphtha, bisulfate of carbon, ether, wood elcohol or other cleaners. When these are thoroughly dried out .5. cover the fabric with heavy coatings of vulcanizehle rubber cement by passing it once or twice through the cemenj; so cs to thoroughly saturate the fabric, and then between pressure rollers to force in the liquid and express the surplus. 1 then so ply over 'i'his prepared iii-accrual s. chin layer hr sheet 6 of vulcenizehle rubher compound and roli ii firmly on and into the meshes of the foundation fabric, which fabric in the sh is heizz so ihe iiiner sole B, Fig. 3. Fri- .ierrcore i. greatly strengthen this sol- :cie'torial and somewhat cushion it by iiicorporu with and into it a layer 7, of st r ong some}. or vegetable fiber such. as animal heir, juic, flex, hemp or ov'her siringlike" material, thoroughly cleansed -cnd mixed with rubber cement end rolled or pressed into the vulcenizablesubstances. This is most conveniently done by using an additional sheeh 8 of the compounded oughly mixed with the cemcnu, is spread as Elpccificedon of Letters Patent.

equally as may he and by roller pressure, nizide into a, sheet of first cushion form, the fibrous matter coming between the two layers of vulcenizehle ruhber,-a.ll being subscquently united into one firm body, adopted for soling and other purposes, the heat and pressure of vulcanization. The outer.- most layer 8 forms the bottom of the sole and may he roughened or corrugated by shaping the vulccnizinp; mold accordingly. lhis composite material A, may be cut into sole form by dies or ba-ndcutters and Worked into boots and shoes in. iieu of leather or other substances. In case of pai tied vulcanization While in sheet form the soles out therefrom may have their edges bound with strips of vulcanizable rubber before subjecting them to the final heat. Soies and heels may be formed, in one, from this improved msierial suitable molds, and firmly united to each other and to the shoe by vulcenizafiion with finished edges to avoid showing the material in secln making up this material in sole and heel form I provide, near the sole and heel edges, deep, narrow channels to receive the thread or other fastening, for its protection against wear by direct contact with the ground. Thus sunken the fastening knot cannot become untied. The heel-portion of the sole has vertical holes 10 interseating such channels to receive the permanent fastening means 11 which uniteiii ito the shoe. The edgewise seam 152 which unites the sole marginally to the shoe is iiidicctcd in Figs. 3 and at. This new and improved sole and heel, as an integral structure, may he thou firmly vulcanized so the bofitom of the inner sole of the boot or shoe or otherwise secured in. its Working position. it will he understood that all the rubber parts are in a. vulcaniznbie condition when first assembled and that subsequent vulcanization permanently unites them.

I claim as my invention:

1. A composite water-proof material for shoe soles, embodying a, substzu'iticl upper layer of textile fehric free from grease and saturated with rubber cement, a. layer of rubber compound pressed into the most intimate contact with such layer, a Cl/lSlilUuing body of strong fibrous material intimstely intermixed and saturated with rubber cement and an outer, bottom layer formed of rubber compound, such rub er parts being vulcanizeble when first assembled and all being permanently united into one integral body by vulcanization, substantially as set forth.

. 2. Composite shoe-soling material, made in sole and heel form, embodying an upper layer of strong textile fabric saturated with rubber cement, a coating of rubber comby subsequent vulcanization,

pound in'intimate contact with a cushioning layer formed of animal hair thoroughly intermixed with heavy rubber cement, and a bottom layer of rubber compound forming the outer layer of the sole,

' the rubber parts being vuloanizable when and having a sheet of rubber compound epsuch fabric,

plied thereto, acushioning body or layer of fibrous or string-like material, thoroughly intermixed with strong rubber cement, and a bottom or outer layer of rubber compound covering said material, such rubber arts being vulcanizable When first assemble and all subsequently vulcanized firmly together,

the sole and heel margins being deeply grooved to receive the fastenings for uniting -the sole to the shoebody and the'heel haV-- ing vertical perforations extending through it and intersecting such groove to receive the heel fastenings, substantially as set forth.

In'testimony whereof I have afiixed my,

signature, in presence of two Witnesses.
